Hi,

The data is maintained in masters like material & vendor master.

Those will be created using MM01 (Material) & XK01 / MK01 (Vendor)

Starts with Purchase Requisition. This is request for Material/ Services. Usually raised by users.

ME51N: Create Purchase Requisition (PR): Using this transaction one creates the PR.

ME52N: Change PR. Using this transaction, one can change the existing PR/ add some more data to it.

ME53N: Display PR. This transaction is just for display purpose. One cannot change/ add any data.

Once the PR is created -> It goes through release procedure (if you have one). "Release" means approval of the PR (T-code: ME54N / ME55).

Once it is released, the next step is Request for Quotation (RFQ).

ME41: Create RFQ: Using this transaction one creates the RFQ.

ME42: Change RFQ. Using this transaction, one can change the existing RFQ/ add some more data to it.

ME43: Display RFQ. This transaction is just for display purpose. One cannot change/ add any data.

Request for Quotation is a means of getting quotations from prospective vendors.

Once the vendors submit their quotations, you can update the RFQ's with the respective quotations using ME47.

Once can even do analysis of quotations / comparative statement (T-code: ME49).

This helps in deciding on the vendor. Once this is done, the Purchase order is created on the selected vendor.

ME21N: Create Purchase Order (PO): Using this transaction one creates the PO.

ME22N: Change PO. Using this transaction, one can change the existing PO/ add some more data to it.

ME23N: Display PO. This transaction is just for display purpose. One cannot change/ add any data.

Once the PO is created -> It goes through release procedure (if you have one).

ME29N / ME28 : Release of PO

After PO is created and released then material receipts / issues will be done throug t-code: MIGO

Creatio of Reservation for issue : MB21

hi,

Sources could be

Source list, quota arrangement, or any other exsisting doc...

simple process :

1. MAke the MMR - MM01

2. Generate VMR - MK01 or XK01

3. Then create PR from ME51N

4. Create PO from ME21N

5. Then do GR ie. goods receipt from MIGO

6. Then Do IR ie. invoice receipt from MIRO
